Kp Calculator
Convert between $K_c$ and $K_p$ for gas-phase reactions
Formula: $K_p = K_c(RT)^{\Delta n}$
Where $R = 0.08206\text{ L·atm/(mol·K)}$, $T$ is absolute temperature, and $\Delta n$ is the difference in stoichiometric coefficients of gaseous products and reactants.
Where $R = 0.08206\text{ L·atm/(mol·K)}$, $T$ is absolute temperature, and $\Delta n$ is the difference in stoichiometric coefficients of gaseous products and reactants.

Calculation Results
⚠️ When calculating $\Delta n$, only count the stoichiometric coefficients of substances in the gaseous phase (g). Solids (s), liquids (l), and aqueous (aq) species do not contribute to $\Delta n$ or gas partial pressures.
